Who even made the rule that we cannot group ducks and fish together for the simple reason that they are both aquatic? If I want to group them that way and it serves my purpose then I can jolly well do it however I want to and it is still a nested hierarchy and you can't tell me that it's not.

People say that I am an idiot because they don't bother to try understand what I'm saying and question their own beliefs.

But you say such idiotic things, and ignore evidence contrary to your beliefs, and almost always ignore all requests for detailed elucidation of the idiotic statement in question. If you aren't prepared to offer backup for a prima facie outlandish display of idiocy, then you have to be prepared to be considered an idiot.
